INTELLIGENT SIGNAL AMPLIFIER OPERATION MODE CONFIGURATION METHOD AND APPARATUS, AND DEVICE

TECHNICAL FIELD

This application pertains to the field of communications technologies, and specifically relates to an intelligent signal amplifier operation mode configuration method and apparatus, and a device.

BACKGROUND

An intelligent signal amplifier is used to extend the coverage area of a cell and has functions mainly including: receiving and amplifying downlink signals from a base station to enhance the strength of the signals reaching a UE, and amplifying uplink signals from a UE to enhance the strength of the signals from the UE to a base station. The intelligent signal amplifier can be controlled by a base station. That is, the base station can control transmission parameters of the amplifier, for example, power-on/-off, transmitted beams, and the like of the intelligent signal amplifier, so as to increase the signal power of the amplifier and reduce interference. In a network structure shown in FIG. 1, three network nodes are included, and the intermediate network node is an intelligent signal amplifier, which includes a mobile termination (MT) and a radio frequency module. The MT is used to establish a connection with a base station, and the base station interacts with the intelligent signal amplifier through the MT so that transmission parameters of the intelligent signal amplifier can be configured.

However, existing intelligent signal amplifiers rely on configuration at the base station. After being powered on, the intelligent signal amplifier continuously operates, typically only amplifying or forwarding full-carrier uplink and downlink signals, and the operation mode cannot be adjusted. In this case, signals are still forwarded in a full-carrier and full-time manner in the event of low network load, causing greater power consumption and higher electricity loss of the network.

In addition, “and/or” in this specification and claims indicates at least one of connected objects, and the symbol “I” generally indicates that the associated objects are in an “or” relationship.

It should be noted that the technologies described in the embodiments of this application are not limited to long term evolution (LTE)/LTE-Advanced (LTE-A) systems, and may also be used in other wireless communications systems, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency-division multiple access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are usually used interchangeably. Techniques described herein may be used in the afore-mentioned systems and radio technologies, and may also be used in other systems and radio technologies. In the following descriptions, a new radio (NR) system is described for an illustration purpose, and the NR term is used in most of the following descriptions, but these technologies may also be applied to other applications than an NR system application, for example, the 6th generation (6G) communications system.

FIG. 1 is a block diagram of a wireless communications system to which embodiments of this application are applicable. The wireless communications system includes a terminal 11, an intelligent signal amplifier 12, and a network-side device 13.

The intelligent signal amplifier is used to extend the coverage area of a cell and has functions mainly including: receiving and amplifying downlink signals from a network-side device to enhance the strength of the signals reaching a terminal, and amplifying uplink signals from the terminal to enhance the strength of the signals from the terminal to the network-side device. The intelligent signal amplifier can be controlled by the network-side device. That is, the network-side device can control transmission parameters of the intelligent signal amplifier, for example, power-on/-off, transmitted beams, and the like of the intelligent signal amplifier, so as to increase the signal power of the intelligent signal amplifier and reduce interference.

For example, signals/channels that need to be amplified by the intelligent signal amplifier may include:

- cell discovery signals: primary synchronization signals (PSS), secondary synchronization signals (SSS), and master information blocks (MIB);
- physical downlink control channels (PDCCH) and physical downlink shared channels (PDSCH) used for sending information to users;
- PDCCHs and PDSCHs used for system information broadcasting;
- physical random access channels (PRACH); and physical uplink control channels (PDCCH) and physical uplink shared channels (PDSCH) used to send uplink user information.

For example, the intelligent signal amplifier includes a terminal module (MT) and a radio frequency module (RU) (also referred to as a radio frequency unit). The MT is used to establish a connection with the network-side device, and the network-side device interacts with the intelligent signal amplifier through the MT so that transmission parameters of the intelligent signal amplifier can be configured. Typically, after being powered on, the intelligent signal amplifier continuously operates, amplifying or forwarding full-carrier uplink and downlink signals without considering whether a carrier carries a signal that needs to be forwarded. In this case, signals are still forwarded in a full-carrier and full-time manner in the event of low network load, causing greater power consumption and higher electricity loss of the network.

For example, the terminal 11 may also be referred to as a terminal device or user equipment (UE), and the terminal 11 may be a terminal-side device, such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer or a notebook computer, a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device or vehicle user equipment (VUE), or pedestrian user equipment (PUE). The wearable device includes: a smart watch, a wrist band, earphones, glasses, or the like.

It should be noted that a specific type of the terminal 11 is not limited in the embodiments of this application. The network-side device 12 may be a base station or a core network. The base station may be referred to as a NodeB, an evolved NodeB, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a NodeB, an evolved NodeB (eNB), a home NodeB, a home evolved NodeB, a WLAN access point, a Wi-Fi node, a transmission and reception point (TRP), or another appropriate term in the art. Provided that a same technical effect is achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of this application, the base station in the NR system is merely used as an example, and a specific type of the base station is not limited.

The following describes in detail the intelligent signal amplifier operation mode configuration method and apparatus provided in the embodiments of this application by using some embodiments and application scenarios thereof with reference to the accompanying drawings.

FIG. 2 is a flowchart of an intelligent signal amplifier operation mode configuration method according to an embodiment of the present invention. As shown in FIG. 2, the operation mode configuration method according to this embodiment of this application may include step 201 to step 203.

Step 201. A network-side device sends operation mode configuration information to an intelligent signal amplifier.

Step 202. The intelligent signal amplifier receives the operation mode configuration information from the network-side device.

Step 203. The intelligent signal amplifier sets a target operation mode based on the operation mode configuration information.

In this embodiment of this application, the operation mode configuration information is used for configuring N operation modes for the intelligent signal amplifier. The N operation modes include at least one of the following: frequency-domain operation mode or time-domain operation mode; and the target operation mode is at least one of the N operation modes.

In this embodiment of this application, one frequency-domain operation mode corresponds to one set of frequency-domain operating subband configuration parameters; and one time-domain operation mode corresponds to one set of operation window configuration parameters.

In this embodiment of this application, the operation mode configuration information is at least used to configure an operation mode of a radio frequency unit for signal forwarding in the intelligent signal amplifier.

For example, regarding the frequency-domain operation mode in this embodiment of this application, one or more operation modes (for example, schematic diagrams of operation modes corresponding to Mode 1, Mode 2, Mode 3, and Mode 4 shown in FIG. 3) for different operation bandwidths may be configured by the network-side device for the intelligent signal amplifier. Generally, an operation mode for a narrow operation bandwidth is activated in the case of low system load, and an operation mode for a broad operation bandwidth is activated in the case of high system load. In FIG. 3, Mode 1 is used in the case of lowest load, Mode 2 is used in the case of medium load, and Mode 3 is used in the case of high load.

In FIG. 3, Mode 1, Mode 2, and Mode 3 show three different operating subbands (namely, operation bandwidths (Operation bandwidth)) configured by the network-side device for the intelligent signal amplifier based on system load in a case that the intelligent signal amplifier operates at corresponding carrier bandwidths (Carrier bandwidth). This can satisfy the needs of signal forwarding while reducing power consumption. Similarly, it can be known from Mode 4 in FIG. 3, two different operating subbands are configured for Mode 4, and Mode 4 may be used in a case that bandwidth parts (Bandwidth Part, BWP) of different UEs being served are configured to be within different frequency ranges.

Optionally, in an embodiment of this application, each operation mode corresponds to a forwarding power configuration parameter.

Optionally, in an embodiment of this application, the time-domain operation mode and the frequency-domain operation mode are allowed to be configured simultaneously and to be in an active state simultaneously.

Optionally, in this embodiment of this application, the operation mode configuration information is activated or deactivated by the network-side device through system information, RRC signaling, MAC signaling, or PHY signaling; where the PHY signaling is a PDCCH order, the PDCCH order is used to define a target radio network temporary identifier (RNTI), and the target RNTI is used to activate or deactivate the operation mode configuration information.

Optionally, in this embodiment of this application, in a case that the operation mode includes the frequency-domain operation mode, the operation mode configuration information includes at least one of the following: a start point and an end point of an operating subband corresponding to the frequency-domain operation mode; and power spectral density, transmit power, or signal amplification multiple of the operating subband.

- a start point and an end point of an operation window corresponding to the time-domain operation mode;
- a length of the operation window; or
- a cycle of the operation window; where
- the start point of the operation window is configured with respect to an offset parameter for a time point.

For example, the network-side device may directly configure one operation window of the intelligent signal amplifier based on needs, including a start point, a length/end point, and transmit power density. The start point may be explicitly configured using a parameter or defined as the time when a configuration command is received. When an operation window ends, a non-operating state resumes.

Optionally, in this embodiment of this application, the time-domain operation mode includes at least one of the following:

- first time-domain operation mode;
- continuous operation mode;
- discontinuous operation mode; or
- composite time-domain operation mode; where
- the first time-domain operation mode satisfies any one of the following:
- downlink (DL) only supports amplification or forwarding of a transmit interval of a synchronization signal/physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH block, SSB) or a CSI reference signal (CSI-RS) used to detect a signal; and
- uplink (UL) only supports amplification or forwarding of a PRACH transmit window;
- the composite time-domain operation mode is a time-domain operation mode obtained by combining multiple time-domain operation modes that are configured by the network-side device for the intelligent signal amplifier; and
- each time-domain operation mode includes at least one operation window.

Further optionally, in this embodiment of this application, in a case that the first time-domain operation mode is a lowest time-domain operation mode, the lowest time-domain operation mode may include one or more periodic operation windows. It should be noted that the first time-domain operation mode is intended to provide at least cell discovery signal coverage and random access signal coverage during low network load.

Further optionally, in this embodiment of this application, an operation window corresponding to the first time-domain operation mode (for example, the lowest time-domain operation mode) is determined based on any one of the following:

- a window for forwarding target information determined by the intelligent signal amplifier based on the detected target information; and
- a PRACH resource window of a cell detected by the intelligent signal amplifier; where
- the target information includes at least one of the following: SSB, CSI-RS, PRACH signal, or cell broadcast information.

For example, methods for determining the operation window corresponding to the first time-domain operation mode include at least the following two methods.

Method 1. The intelligent signal amplifier may autonomously determine the operation window corresponding to the lowest time-domain operation mode.

For example, the intelligent signal amplifier may determine a window for forwarding an SSB signal based on a detected SSB, or may determine a window for forwarding a PRACH signal based on received PRACH configuration.

Method 2. The intelligent signal amplifier may receive forwarding window configuration from the network-side device. Configuration for sending/forwarding a CSI-RS used as a discovery signal is included.

For example, in a scenario of the first time-domain operation mode, in downlink it is for only for amplification or forwarding during a transmit interval of SSB or CSI-RS signal for discovery. FIG. 4 shows a schematic diagram of several operation windows for downlink forwarding. Three downlink operation windows for SSB signal forwarding (DL operation window for SSB signal forwarding), as well as a cycle of an SSB operation window (SSB cycle), are included.

For example, in a scenario of the first time-domain operation mode, in uplink it is only for amplification or forwarding in a PRACH transmit window. FIG. 4 shows a schematic diagram of several operation windows for uplink forwarding. In a case that at least one PRACH is included, two uplink operation windows for PRACH signal forwarding (UL operation window for PRACH signal forwarding), as well as a cycle of a PRACH operation window (PRACH window cycle), are included.

Further optionally, in this embodiment of this application, regarding the discontinuous operation mode, one or more time-domain may generally be configured for the intelligent signal amplifier, and a sequence number may be configured for each operation mode. Configuration information corresponding to the discontinuous operation mode configuration may include: a start point, an end point, and a length of an operation window, and an operation cycle of the operation window. An offset parameter for a time point corresponding to the start point of the operation window may be referred to as offset.

For example, refer to a schematic diagram of the discontinuous operation mode shown in FIG. 5. In FIG. 5, the horizontal axis is time, and three operation windows (Operation window) are included in the horizontal axis of time. In addition, FIG. 5 further shows a cycle of the discontinuous operation mode of an RU (RU discontinuous operation cycle), and a start point, an end point, and a length of each operation window. An offset parameter for a time point corresponding to this operation mode is offset.

Further optionally, in this embodiment of this application, regarding the composite time-domain operation mode, the composite time-domain operation mode may be a time-domain operation mode obtained by combining multiple time-domain operation modes that are configured by the network-side device for the intelligent signal amplifier. For example, while the lowest time-domain operation mode stays active for the intelligent signal amplifier, the operation mode shown in FIG. 5 is activated.

It should be noted that in this embodiment of this application, the time-domain operation mode and the frequency-domain operation mode are allowed to be configured simultaneously and to be in an active state simultaneously. In this case, the intelligent signal amplifier is in the composite time-domain frequency-domain operation mode.

Optionally, in this embodiment of this application, in a case that the operation mode includes the time-domain operation mode, the method provided by this embodiment of this application further includes step 204.

Step 204. The intelligent signal amplifier adjusts a parameter of an operation window corresponding to the target time-domain operation mode.

In an example, the intelligent signal amplifier can autonomously adjust the time-domain operation mode, for example, autonomously adjusting a length of an operation window of a time-domain operation mode or extending an operation window based on a forwarding parameter configured by the network-side device.

In this way, the intelligent signal amplifier can adjust the time-domain operation mode flexibly based on system load, so as to achieve effective use of system power.

Optionally, in this embodiment of this application, step 203 may include step 203a.

Step 203a. The intelligent signal amplifier activates, deactivates, or switches to a target operation mode based on the operation mode configuration information.

For example, in a case of setting a target operation mode, the intelligent signal amplifier may set the target operation mode based on an instruction sent by the network-side device, or autonomously and adaptively adjust the operation mode. This is not limited in this embodiment of this application.

Optionally, in this embodiment of this application, as shown in FIG. 6, step 203 may include step 203b1 to step 203b3.

Step 203b1. The network-side device sends a target instruction to the intelligent signal amplifier.

Step 203b2. The intelligent signal amplifier receives the target instruction from the network-side device.

The target instruction is used to indicate the intelligent signal amplifier to perform a target operation.

Step 203b3. The intelligent signal amplifier performs a target operation based on the target instruction and the operation mode configuration information.

The target operation includes activating, deactivating, or switching to the target operation mode.

For example, operation mode switching may be implemented based on an explicit instruction from the network-side device. The network-side device (for example, a base station) sends an operation mode switching command to an RU through the MT, and the switching command carriers a target operation mode. After receiving the switching command, the RU switches to the target operation mode. Upon receipt of the operation mode switching command, the MT sends to the network-side device a response message indicating that the switching command is received.

In an example, the intelligent signal amplifier may receive a time-domain operation mode switching instruction from the network-side device, and switches from the continuous operation mode to another discontinuous operation mode.

In another example, the intelligent signal amplifier may receive from the network-side device a time-domain operation mode activation or deactivation instruction for activating or deactivating one or more time-domain operation modes.

Optionally, in this embodiment of this application, the intelligent signal amplifier can autonomously adjust the operation mode.

For example, step 203 may include step 203c1.

Step 203c1. The intelligent signal amplifier switches to the target operation mode based on bandwidth scheduled by the network-side device and the operation mode configuration information.

For example, the intelligent signal amplifier switches to the target operation mode matching the scheduled bandwidth based on the bandwidth scheduled by the network-side device and the operation mode configuration information, in a case that the bandwidth scheduled by the network-side device exceeds current operation bandwidth of the intelligent signal amplifier or an absolute value of a difference between the bandwidth scheduled by the network-side device and the current operation bandwidth of the intelligent signal amplifier is greater than or equal to a predetermined threshold.

For example, the bandwidth scheduled by the network-side device is determined based on at least one of the following:

- an operation bandwidth indicated by the network-side device;
- a subband bandwidth indication carried when the network-side device configures a beamforming parameter for any one operating subband of the intelligent signal amplifier; or
- a subband bandwidth indication carried when the network-side device configures a transmit power spectral density parameter for any one operating subband of the intelligent signal amplifier.

Optionally, in this embodiment of this application, the intelligent signal amplifier operation mode configuration method provided in this embodiment of this application further includes step 205.

Step 205. The network-side device activates or deactivates the operation mode configuration information through system information, RRC signaling, MAC signaling, or PHY signaling.

The PHY signaling is a PDCCH order, the PDCCH order is used to define a target RNTI, and the target RNTI is used to activate or deactivate the operation mode configuration information.

For example, the operation mode configuration information may be sent by the network-side device to the intelligent signal amplifier through RRC signaling, and then the network-side device performs activation/deactivation through MAC/PHY signaling.

In the intelligent signal amplifier operation mode configuration method provided by the embodiments of this application, the intelligent signal amplifier receives operation mode configuration information from the network-side device, and sets a target operation mode based on the operation mode configuration information, where the operation mode configuration information is used for configuring N operation modes for the intelligent signal amplifier. The N operation modes include at least one of the following: frequency-domain operation mode or time-domain operation mode; and the target operation mode is at least one of the N operation modes. In this way, the network-side device can configure different operation mode information for the intelligent signal amplifier based on different network loads, or the intelligent signal amplifier adaptively switches between operation modes, avoiding power consumption and electricity loss and reducing interference with the intelligent signal amplifier.

It should be noted that the intelligent signal amplifier operation mode configuration method provided by this embodiment of this application may be performed by an intelligent signal amplifier operation mode configuration apparatus, or a control module of the intelligent signal amplifier operation mode configuration apparatus for performing the intelligent signal amplifier operation mode configuration method.
